'I Claims.

railway cars and more particularly to that type of car employed in the transportation of coal or ore from the source of supply to a point of distribution.

In the case of coal mines the veins of coal usually run beneath the ground at such a distance so as to employ the burrowing of a tunnel. These tunnels or larteries are madeof a sectional area slightly larger than the cross sectional area of coal to be mined and are therefore limited as to the distance between the side walls. It is one of the objects of the present invention to construct a car of maximum width in order to increase the capacity of the car.

It is also found inmany mines that the vein of coal is rather thin and consequently the head room or ceiling of the arteries are made appreciably low. It is therefore another object of the present inventionto construct a mine car of less height than the usual type of mine cars without diminishing the capacity of the car.

Another object of the invention is the provision of the oor of the car close to the rails so as to lower the center of gravity of the car with respect to the rails, thereby imparting a greater amount of stability to the car in addition to increasing the capacity thereof.

Another object of the invention is the provision of a rigid, durable construction.

These and other objects will become apparent to one skilled in the art from the following description.

,In the drawings which form a part of the present description, Fig. 1 shows a plan view of the mine car embodying the improvements of the present invention; Fig. 2 shows a part sectional and part side elevational view taken along line 2 2 of the car showndn Fig. 1; Fig. 3 is an end elevation of the car shown in Fig. 2; Fig. 4 is an enlarged cross sectional view taken along the lines 4 4 of Fig. l and Fig. 5 is a cross sectional view taken along the lines 5 5 of Fig. 1.

Referring now in detail to the drawings wherein like characters refer to like parts, I indicates a mine car having side walls 2, a floor 3, and end walls 4. The side walls 2 are made up of a girder plate 5 and side plate 6 extending substantially the full length of the car body. 'I'he girder plate 5 extending in the same vertical plane from the bottom of the car body toa point below the top edge thereof, has the top portion I inclined inwardly within the car body relation to the body of the plate 5. Secured 'Ihe invention pertains to the construction of to the indent upper portion of the side girder formed by the inclined portion I and vertical flange 8 is a side plate 6, the latter being preferably Z-shaped having a horizontal flange 9 and oppositely disposed vertical flanges I0 and 5 II. 'Ihe upwardly directed flange II of the side plate 6 lies against and is attached to the ange 8 of the side girder plate by rivets I2. The downwardly extending flange I0, preferably lying in the same vertical plane as the body of the l0 side girder plate 5, is connected thereto as at I3, by means of a weld or any other desirable method. It will be noted that the side plate 6 together with the portion 1 and flange 8 of the side girder plate 5 forms a rigid truss member 15 along the upper edge of the car side 2.

The floor plate 3, extending the full length and across the bottom of the car, lies in the same horizontal plane a slight distance above the ,tops of the rails. Marginal flanges I4 formed 20 along the-outer edge of the plate 3 and inclined upwardly, overlapping the girder plates 5 and connected thereto by means of rivets.

Adjacent the center of the car and extending longitudinally thereof, beyond the end walls 4, 25 are oppositely disposed angular sills I5. These sills are preferably formed of commercially rolled bulb angles having a horizontal inwardly directed flange I8 resting upon and secured to the floor plate'3 and a vertical flange I'I directed within 30 the body of the car. In order to strengthen the sillsv I5 against compressive forces due to end shocks, cross ties I8 are located preferably at ther center line of the axles. 'I'hese cross ties are preferably formed of angles having a horizontal flange I9 resting upon and secured to the floor plates 3 and a vertical flange 20 which is `connected with the vertical anges I1 yof the sills I5. l

A pair of spaced angular members 2l resting upon the floorplate 3, adjacent the center line of each axle, extend between the sills I5 and the side girder plate 5 and are connected thereto by angles 22-22. Secured to the angular members 2| intermediate their ends and to the floor plate 3 is an angular support 23. Attached tothe angular members 2| adjacent the tops thereof and to the angular support 23 'are sub-floor plates 24 having an upwardly directed ilange 25 abutting and attached to the side girder plate 5. Wheel hoods 26 completing the sub-floor span 'the space from the angular support 23 to the sill I5. The wheel hoods 26 are formed of a plate having an arched central portion 2l extending Within the car body and marginal anges 28 connected to the sub-floor plate 24, spaced angular members 2| and sill I5.

It will be observed from Fig. 4 that gussets 29 functioning as a diagonal brace connecting the side girder 5, sub-floor plate 24 and wheel hoods 26 form a rigid and durable construction. The gussets 29 formed of a plate 30 having opposite vertically disposed flanges 3|-32 are connected to the side girder 5 and the side wall 33 of the arched central portion 21 of the wheel hood 26 respectively. The top portion of the flange 3I is directed inwardly and upwardly to a point adjacent the top of the girder plate and is secured to the flange 8 of the girder plate 5 and flange II of the side plate 6. The flange 34 of the gusset 29 connects the flanges 3|-32 and is secured to the sub-floor plate 24.

'Ihe oor plate 3 has apertures 35 directly beneath the wheel hoods 26 and defined inwardly of the car by the support 23, sill I5 and the spaced angular members 2| for the reception of stub axled wheels 36 which are mounted in open bottom bearings 31 secured to the supports 23 and sills I5.

'I'he end walls 4, having a reinforcing curled portion 38 along the top edge thereof, extend between and arel secured to the side walls 3. The side portions 39 being tapered to allow for clearance between the ends of two such cars coupled together when turningl a sharp bend which is frequently found in tracks leading from deposits to the points of distribution. Angular members 40 connect the tapered portions 39 to the floor plate 3 and the members 4I connect the end wall 4 to the floor` plate intermediate the sills I5. Reinforcing angles 42 extend substantially the full height of the end wall 4 along the inner face thereof forming a connec tion between the end wall 4, sills I5, and angular members 48, in addition to reinforcing the end walls adjacent the center of the car.

The composite bumper 43 extending between the sills I5 outwardly of the end wall 4 is sup- DOrted by the .backing angle 44 which abuts the end wall and is connected to the intermediate portion of the end wall and floor member 4I superimposed upon the bumper and rearwardly of the front face thereof is a channel shaped draft sill 45 extending across the sills I5 andV having a lower flange 46 secured to the sills by clips 41. the end Wall is secured to the end wall 4 and the reinforcing angles 42.

0n the longitudinal medial line and at one end of the car a resilient drafting device 49 is positioned in the draft sill 43 and having a portion 50 thereof extending into the body of the car.
